Propensity scores are commonly used in observational research. This article provides a brief introduction to propensity scores aimed for resuscitation researchers. We discuss the concept and calculation of the propensity score and how it can be used to adjust for confounding via regression adjustment, stratification, weighting or matching. The interpretation of these method is briefly discussed and the advantages and limitations of propensity scores are presented. Lastly, we provide some practical recommendations for the presentation of studies using propensity scores.
倾向评分在观察性研究中被广泛应用。本文旨在为复苏研究人员提供倾向评分的简要介绍。我们讨论了倾向评分的概念和计算方法，以及如何通过回归调整、分层、加权或匹配来调整混杂因素。本文简要讨论了这些方法的解释，并介绍了倾向评分的优点和局限性。最后，我们提供了一些使用倾向评分的研究报告的实用建议。
